Thats the problem. When i close the tab, everything is exactly unchanged. Ex : i 've unchecked zemanta to enable the browser plugin to work, but when i open the tag again, its marked (along with other unchanged options that i've made to test)

Very sorry to hear about the troubles you are having saving your screen options. I was able to recreate the issue that you are having and I'm gathering more information. I will follow up once I know more.

Hi there,
I am working on knightsanddamsels.wordpress.com and I am trying to get a nice customized theme, with a nice background as well. however, even if the changes I made are supposed to be saved, they are not applied to mu blog. the same happens with the twitter and facebook buttons I am trying to integrate in the blog. could you please give me a hand? i am a bit desperate!
